1 /** @file 2 EDKII Platform Has Device Tree GUID 3 4 A NULL protocol instance with this GUID in the DXE protocol database, and/or 5 a NULL PPI with this GUID in the PPI database, implies that the platform 6 provides the operating system with a Device Tree-based hardware description. 7 Note that this is not necessarily exclusive with different kinds of hardware 8 description (for example, an ACPI-based one). A platform driver and/or PEIM 9 is supposed to produce a single instance of the protocol and/or PPI (with 10 NULL contents), if appropriate. 11 12 Copyright (C) 2017, Red Hat, Inc. 13 14 This program and the accompanying materials are licensed and made available 15 under the terms and conditions of the BSD License that accompanies this 16 distribution.
